Feature with ID ‘87294c72-f260-42f3-a41b-981a2ffce37a’ is not installed in this farm, and cannot be added to this scope. Error creating SharePoint site collection, Powershell

I had an error today when I created my farm via PowerShell. I forgot to run the SharePoint Products and Configuration Wizard (PSConfig) after creating the farm. The result was an error when creating site collections via the UI, as well as subsites via the UI. I could only create the sites via PowerShell and I got quite a few errors in the UI and had to navigate to http://intranet/_layouts/settings.aspx to get the site to load without an error.

Sorry, something went wrong.

Technical Details

ULS shows this error creating a subsite under the root site collection via the UI: “Failed to apply template “STS#0” to web at URL “http://intranet.com/Test&#8221;, error Feature with ID ‘guid’ is not installed in this farm, and cannot be added to this scope.”

Solution: Run PSConfig, then try creating your site in the UI.

If you created the sites via PS and want to delete them, I had to do get-spsite | remove-spsite (THIS REMOVES ALL SITE COLLECTIONS). Then I ran PSConfig and recreated the Site Collections via PowerShell successfully.

You can run the following command:

Install-SPFeature –AllExistingFeatures

via powershell, but there are other commands as well that must be ran that PSConfig performs:
